Abstract

The invention provides a high-temperature-resistant modified asphalt waterproof coiled material and a preparation method thereof. The modified asphalt waterproof coiled material comprises a tread baselayer, prepreg, a coating material and an isolating material; the tread base layer of the modified asphalt waterproof coiled material is fiberglass mesh cloth and polyester fiber composite tread base; and the prepreg is prepared from the following raw material components: 130# asphalt, chlorinated rubber, ethylene-vinyl acetate glyceride, elm tree wood powder and an anti-ageing agent. The modified asphalt waterproof coiled material has excellent thermal stability, thermal ageing resistance and low-temperature flexible performances.

Description

technical field [0001] The invention relates to a high-temperature-resistant modified bitumen waterproof coiled material and a preparation method thereof, belonging to the technical field of waterproof coiled materials. Background technique [0002] The waterproof membrane products on the existing market in my country are mainly composed of three series, modified bitumen waterproof material, polymer plastic waterproof sheet and synthetic rubber waterproof membrane. The modified asphalt waterproofing membrane is made of rubber modified petroleum asphalt as the impregnated covering layer, made of polyester fiber non-woven fabric, jute cloth, glass fiber mat, etc. , batching, co-melting, impregnation, composite molding, curling and other processes. Modified asphalt waterproof membrane can be divided into two types according to the base: polyester tire and glass fiber tire; according to the covering material, it can be divided into four types: PE film (aluminized film), colored...
